Soil health plays a crucial role in shaping the flavor profiles of locally produced seasonal foods by influencing the soil’s microbial communities, especially fungi. These microbes, adapted to local soil conditions—like pH, nutrients, and organic matter—can transfer unique flavor characteristics from the soil to plants through pathways such as the xylem. This movement is especially apparent in wine production, where soil fungi bring region-specific aromas to grapes, significantly impacting wine’s flavor profile (Liu et al., 2020).
Compared to bacteria, fungi contribute more directly to unique flavors because of their strong role in fermentation. During fermentation, fungi produce esters and acids that reflect the soil’s specific attributes, leading to distinct sensory profiles that embody the “terroir” of the region. Environmental factors, such as temperature and rainfall, further influence this microbial diversity, helping cultivate flavors that are unique to their soil and climate. In this way, healthy soils rich in microbial diversity support more nuanced, unique, region-specific flavors, enhancing the quality and marketability of seasonal foods (Liu et al., 2020).
